FOLDING BED.

.Application filed July 15,

This invention relates to improvements in portable folding beds, adaptedfor camping purposes, and-moreparticularly to a type of bed wherein theside rails and legs of'the bed are composed of channel bars, each siderail composed of a central bar and pivoted end bars which'fold withinthe central bar, and the legs being adapted to fold around the back andsides ofthe central bar. The present invention relates more particularlyto the means for fasteningthe legs to the end bars of the side rails,whereby the bed fabric may be stretched taut, after the bed has been setup, witha minimum of effort, and whereby the stretching devices foldwithin end bars of the siderails; also to improvements in the leg tieswhich extend betweenthe legs attached to'each side rail, and to theconstruction of the side'rails, whereby the ties fold in grooves in thebaclrsof said rails; also to improvements in theforms of the severalchanneled parts, whereby said parts fold and unfold with a minimumamountof friction, and to certain other details of construction whichwill be-hereinafter pointed out. i T

The bed frame comprises side railsaand. a, of channel steel, eachsiderail composed of 'a' relatively long central'bar land endbars 2' and2 ,which are pivotally connected to the centralbar. lVithin the endbars, at their outer ends, are arrangedadjustable extensions 0, adaptedto. engage end bars on a fabric indicated in dotted linessat (Z. These192?. Serial No; 206,097.

extensions are likewise of channeled steel, each extension laid with oneside against the back wall of an end bar, as shown in Figs. l and 6, oneside of each extension-piece being cut off, as indicated at c, to form astop and the other side of the cxtensionpiece being extended beyond thisstop, as shown at 0 to enter a slot in an end bar of the fabric. Eachcentral bar has legs 3, pivotally con nected to its ends. The end barsare pivoted within the central bars upon pivots 4, and when the bed isset up the channeled sides of the central bars face upwardly, and thechanneled sides of the end bars face downwardly, as-shown in Figs. 1 andl. The legs are forked at their upper ends so as-to fit againstthe-outer sides of the central bar, and pivot pins 5 secure the legs tothecentral bars. l he channeled sides of the legs at opposite ends-of acentral bar face one another when thebed is set up. Each end bar foldswithin the central bar, as shown in Figs. 5, (5, 8 and 11, with itschanneled side facing the same way as the centralbar, and each leg foldsaround the back and sides of the central bar, as shown in Figs. 5 and 9.Thelegs attached to each side railiare connected together about midwayoftheir lengths :by a tie Z), comprisingthree sections, namely,- arelatively long central section 6, composed of a flat metal band, andend sections 7, the latter being secured tonthe legs by'pivot pins'8l Asshown in Figs. 7 and 10, each end section comprises afiatbar having,central longitudinal slots 7 and 7 and having parts 7 and 7 struck upfrom the metal to provide openings through which the pivot pin 8 may beinserted. to secure the section to the leg. The end of each sectionadjacent its pivotalp'oint is bentover at right angles to the body ofthe section to form a stop 7. VVhenthe bed is'u11folded=,.the stops7rest against the back walls' of the legs, as shown in Figs.- l and 10,and these stops prevent the end sections of the ties from saggingdownwardly below their pivotal points while the bed is being folded-orunfolded. When the bed is folded, the end sections 7 of the ties liewithin the legs, as shown in Figs. 5 and 6, and the central ribbonlikesections 6 lie within shallow grooves 1 which are formed in the backs ofthe central bars of the side rails, and extend throughout the lengths ofsaid bars. The stops 7 be'ar against the backs of the central bars ofthe side rails, at each side of the section 6 of the tie, as shown inFigs. 5 and 6.

The latches 9 and 9, pivoted within the end bars 2 and 9., are adaptedto engage the pivots 8 to fasten the ends bars to the legs. Theselatches extend through slots 3 in the backs of the legs and through theslots 7 in the sections 7 of the leg ties, and each latch has at itsfree end a hooked portion 9" for engaging the pivot pin 8. The latches 9are mounted directly upon pivot pins 10 in the end bars 2. The latches9, as shown in Figs. 4, 6, 8 and 10, are not pivoted directly to the e dbars 2,- but each of said latches is connected by a pivot pin 10, to achanneled lever 11, which lever has one end connected by a pivot pin 12to an end bar. lVhen the lever is in the posit-ion shown in Fig. 4, thepivot pins 8, 12 and 10 are practically in a straight line, with thepivot pin 12 upon which the lever is fulcrum ed between. the two otherpivots. When the lever 11 is moved downward toward the latch 9, thepivot 19 swings about the pivot 12 and this causes the.

latch 9 to move endwise to release its hook from the pivot pin 8. Byrcturningthe lever to the position shown, it is evident that the latchwill be moved in the opposite direction, and the end section 2 of theside rail will be drawn downward, until'the pivot pin 10 is in line withthe pivots 12 and 8. when the lever 11 will be locked. t will beunderstood that the fabric cZ, indicated in dotted lines in Fig. 2,engages the adjustable ends of the end bars 2 and 2, and that in settingup the bed the latches are hooked over the pivot pins 8 on the legs andthe levers 11 are then moved into the position illustrated in Figs. 2and 4, and this has the efiect of stretching the fabric and holding thelegs in their outer positions.

The legs at each end of the bed are connected together by crossed bracerods, each rod comprising a. long section 14, pivotally connected to theupper end of a leg, and a shorter section 14, pivotallyconnccted to thelower end of a leg. The longer sections are pivoted at their crossingpoints, as .shown at 15, and a toggle 16 is connected by pivots 18 and19 to the sections 14. Stops 20 on the sections 14 limit the downwardmovement of the toggle.

i When the bed is set up, as shown in Figs. 14, the legs are tiedtogether and held from spreading by the ties 7). The fabric appliesspring tension to the end sections of the side rails, tending to liftthe stone. but these are held down by the latches 9, which fasten theend sections to the legs. In setting up the bed, final tension is givento the fabric by raising the levers 11 to the positions shown, whichresults in drawing the end sections downwardly toward the legs.

In folding the bed, the toggles 16 at the ends of the bed are broken bypulling upwardly upon them, and the crossed bars are folded by breakingthe joints between their sections 14 and 14 downwardly, and the oppositeside rails and legs of the bed may then be brought close together. Bymoving the hand levers 11' downwardly, the latches 9 will be releasedfrom the pivots 8 on the legs and the tension on the fabric will berelaxed so that the latter may be removed from the end sections of theside rails. The end sections are then folded back into the centralsections and the latches 9 and 9 are folded into the end sections, asillustrated in Figs. 5, 6 and 8. The levers 11 will also fold within theend sections as illustrated in the views just mentioned. The sections 7of the leg ties fold upwardly within the legs, and the latter are thenfolded over and around the backs of the central sections, and thesections (3 of the leg ties then lie within the grooves 1 in the backsof the central sections of the side rails. The crossed braces, which arepivotally connected to the legs. and the tog gles told as shown in Fig.9, against the backs of the legs and close to the central sections ofthe side rails. .Vhen the bed is completely folded, as shown in Figs. 5and 9, it occupies very small space.

In order to avoid unnecessary friction between the channeled foldingparts, the end bars of the side rails are wide enough to fit closelyagainst the side walls of the central bars only at their pivotal ends,the major portions of the end bars being narrower so that they do nottouch said side walls, as-shown in Figs. 5 and 8; also, the levers 11engage the side walls of the end bars only at their pivotal ends, andthe legs 3 fit against the central bars only at their pivotal ends, asshown in Fig. 5.
